The R3G150-AJ05-09 from EBM-Papst is an EC-driven hot air circulation fan, designed for demanding high-temperature applications. The unit is a straight centrifugal fan with dimensions 200×200×160 mm and is powered by an energy-efficient EC motor with RS-485 MODBUS-RTU communication. It is ideal for pellet burners, solid fuel boilers, and similar heating systems where reliable operation is crucial.
The stainless steel impeller can withstand flow medium temperatures up to 250 °C, making the R3G150-AJ05-09 a robust choice for industrial heat recovery and air circulation in high-temperature environments.

Technical specifications
Datasheet (PDF) - download| Product attribute | Value |
|---|---|
| Airflow at 0 Pa | 270 m³/h |
| Speed | 2900 rpm |
| Power | 32 W |
| Frequency | 50/60 Hz |
| Voltage | 230V AC VAC |
| Motor frame | The motor is mounted on a base plate made of galvanized sheet steel with one-sided vibration damping. The mounting position is optional, which provides flexibility during installation in heating systems. The base plate is designed for solid fuel heating systems and ensures stable attachment of the entire fan unit. |
| Casing | steel plate, galvanized support plate |
| Impeller | The fan impeller is made of stainless steel and has 6 blades, making it suitable for high-temperature applications up to 250 °C in the flow medium. The impeller is an open rotor type without condensate drain holes. The diameter is 150 mm and the impeller provides a maximum airflow of 270 m³/h in free air (no back pressure). At 240 Pa back pressure, the airflow is approximately 95 m³/h. |
| Bearing type | ball bearing |
| IP class | IP54 |
| Motor protection | Electronic motor protection |
| Motor code | M3G055-CF |
| Rotation direction | clockwise, viewed towards the rotor |
| Motor type | The motor is an EC (electronically commutated) motor, size 55, designated M3G055-CF. It is designed for single-phase mains, 230 V AC, 50/60 Hz and nominally consumes 32 W at 2900 rpm. The motor has built-in electronic motor protection with thermal overload protection for electronics and motor, soft start, and current and voltage limiting. The insulation class is 'B' and the motor is equipped with an RS-485 MODBUS-RTU interface for control and communication. The rotor surface is thick-film passivated for increased corrosion resistance. |
